Who is writing?

Journal articles are credited to Andrew Stinson Books. They are website editorial content, not personal testimony or a claim of specialist credentials. Andrew Stinson is a pen name. The initial articles and tools were developed with AI assistance, including drafting, source checking and implementation.

Facts and suggestions

Factual claims include links to their sources, with preference for original organizations and official documentation. A practical exercise is an editorial suggestion, not a research-tested intervention unless explicitly identified as such. Examples and miniature puzzles are illustrative or fictional. We do not invent reader testimonials or results.

Dates and changes

Each article shows its publication date. Dates should change only when content is materially updated, not simply to make an article look new. Device instructions and source links can change after publication.

Books and commercial links

This website promotes our own books. Related-book suggestions are identified as coming from our bookshelf. Reading the articles and using the free tools does not require a purchase. Retail purchases take place on Amazon.
